this isn't the product of any introspection, just some speculation.
Many here would say, I think, that they value the site (at least in part) because of what they can learn and/or share.
Well, if that's actually TRUE, and people ARE learning from one another, maybe you're simply seeing the product/result of that, as the more extreme expressions of opinions (and the opinions themselves) slowly get tempered and modified.
If so, the question is whether this leads to the development of more reasonable, intelligent, and accurate opinions (as the conventional wisdom gets defined and re-defined) or instead to a kind of bland and squishy consensus opinion that offends no one because it no longer has the edges to cut with, and gets at no real truth because it seeks peace at all costs.
I don't know the answer to that.
